In the operation of such acylindenthe cylinder is movedtoward the needles and movement of all needles the ends of which engagethe importions of the pattern cardis thus effected, the needle endswhich are opposite the. perforations in the pattern card "and in theside of'the'cylinder being permitted to pass through these perforationsand these I 30 needles thereforeremaining'idle. One disadvantage of thisconstruction is that if there is any slight displacement of the cylinderin its movement toward the needles, one or more of the needles will beout ofalinement with the openings in the side of t-he'cylinder intowhich it is intended they shall enter with the result that'the ends ofthese needles strike the'surface of the said side of the; cylinder andare bent or distorted. The-present in;

vention', therefore, contemplates the provision ofa cylinder of thistype which will not present this'disadvantage and which will,

therefore, ensure against the interruptions and repairs which areoccasioned in the op eration of the old'type of cylinder.

Another disadvantage presented by the old type of cylinder is that, ifthe end of one or more needles strike the side of the cylin-' derinstead of passingthrough the opening or. openings therein and theneedle, or needles,

section "3 is fitted to each end: of

' ent-lybe more fully explained,

is 'orare not in themselves distorted, theside of the casing,- adjacent-to the open ng oropenings is'liable to be dented or otherwisefdistorted," and, as aconsequence, itbeco'mes necessary to completelyreplace =this side of the cylinder or the entire cylinder if thelsidesare integrally connected. Therefore, the present invention has as afurther object to, first, provide afcylinder so constructed that therewill be little likelihood of impact of the cylinder with't-he needlepoints, and, second, to so "construct the cylinderthat'itwillejmbodyfagplurality of members or units'so assembled upon a suitablysupported 'shaft that anyone of the-members may be removed,

if damaged, and anew one substituted there for-without any onsiderabledisturbance of the other members, i t

In order that the shaftl maybemounted forrota;

tion vsuccessively through vquarter turns and these heads constitutingmeans,

6 which is fitted through a slot 7 formed longitudinally in the plate,the screw being threaded into the head 3 and the plate being confinedbetween the side walls of the respective recess so that it may beadjusted longitudinally therein. The recesses 4; open through the innerfaces of the respective heads 3 and therefore, the plates 5 may beadjusted so that one end of each plate may be caused to project greateror less distances beyond and each plate is formed upon this end with apin 8 which is preferably of c'o'noida'l'form, the pins engaging in ringperforations in tapes which are arranged at the margins of the patterncards. These tapes, are common in the art-,and by reason of theirengagement with thepins, constituting means for connecting the pattern.cards in a series and for feeding the cards one by one so as to efiectsuccessive vertical disposal of the sides of the cylinder and SUCCQSSIVBcards in position presentedtoward the needles. As thisarrangementoofcarjds is well known, it has not been illustrated in thedrawing of the present application as the invention resides moreparticularly in the construction of the cylinder.

In order that the shaft 1 may be properly mounted, a. circular head 9 isfitted in each end of the shaft, the shaft ends projecting beyond theouter sides of the heads 3, and a trunnion 10 is formed upon the outerface of each head 9 and located axially with respect thereto. Theprojecting ends of the shaft 1 and the heads ,9 are formed withregistering openings and a tapered key 11 is driven into thesevopenings, at the time of assembling the component parts of the cylinder,so that the trunnion carrying heads 9 are securelyassembled with theends of the shaft, it being understood that the trunnions aremountedinbearings capable of support- 7 ing the cylinder for therotating and-shifting movement above referred to. In order that the endsof the shaft maybe supported in a stable manner after-eachquarterrevolution of the shaft and the cylinder thereon, a rectang'u'larhousing 12 is fitted onto each projecting end of the shaft and isprovided with a 'flange 13 which is secured by screws or otherwise tothe outer faceof the respective head 3. Thishousing may be held in placeupon the shaft through the medium of the key 11 or any other suitablemanner and in order that the housing may be supported upon a slideforbodily'shifting movement of the cylinder, as a whole, rounded runners14 are 'provided extending laterally from the four corners of the flange13, so that two of these runnersare presented at each side of thecylinder, as'a whole, andafter each quarter of a revolution of thecylinder two of the runners at each end of the'cylinder and at that sidethereof which is pressed downthe inner face of the respective head 5wardly, at this time, will engage upon the said slides.

The body of the cylinder is made up of a number of body units which areindicated in general by the number formed centrally with a circularopening 17 the material of the plate being struck up at one side of theplate and about the said opening so as to provide a substantiallycircular spacing flange 18 and, in order, that the plates 16 may befitted to the shaft 1 and held against any rotative displacementthereon, the flange 18 is formed at diametrically opposite points wlthnotches 19, and notches 20,

similarly located, are formed in the plate 16 at corresponding pointsin'the wall of the opening 17 in said plate, the notches 19 and 20, whenthe plates are fitted onto the shaft, receiving the ribs 2 upon theshaft so that the plates areas stated securely held against any rotativedisplacement. Preferably the plates are arranged intwo series and itwill be understood at this point that the fiange 18 of each plate willabut at its edge against that side of the next adjacent, plate oppositethe ide fr m which the flange of the last mentioned plate projects, aspacing collar 21 being fitted onto the shaft 1 atzeach end of theseries. of body units .to. seat between the inner face of the respectivehead 3 and the face of the respective end-most plate 16 of the series sothat this plate will be spaced from the face of, the head 3 and,likewise, the plates will be spaced from one vanother, uniform distancesthroughout the entire assemblage. As above stated it ispreferable toarrange the units 15 in two series and the units of each series arelocated between one of the heads 3 and a spacing member 21 which is ofrectanularmarginal contour andwhich is fitted and held upon the shaft 1in the same manner as arejthe units 15. This member 21 is of a thicknesssubstantially equal to the width of the space between any two of theunits 15 and, due to the peculiar arrangement of the units 15 in whichtheir flanges 18 are, in both series, presented toward the inner ends ofthe series, the flanges of the inner-most units of the two series willabut against the adjacent faces of the member 21,. .The spacing member21 is preferably formed with a groove 22 in each of its four edges andthese grooves commu- 15 and each of which comprises a rectangular metalplate 16 nicate with one another at their ends, and

similar grooves 23 are formed in the heads 3, the grooves 22 accommodatethe intermediate tape of the cards which connects the intermediateportions of the pattern cards,

and the grooves 23 accommodate the side or marginal tapes of-the cards.

The-cards which will be employed in connectionwith. the cylinder of theinvention are, of course, the. same as the cards ordinarily employed inconnection with a rectangular cylinder employed on aV-Jacquard series,the margins of said units constituting the surface of the cylinder.
